Intensive cattle breeding's environmental challenges are prompting shifts to extensive, pasture-based systems, influencing nutrient and pollutant uptake. PTEs are essential and non-essential elements, regularly found in the environment and organisms, and in which unbalances lead to health issues. Hair analysis, a non-invasive method, provides retrospective PTE exposure evaluation. This study aims to understand exposure and species-specific accumulation patterns of PTEs in cattle and roe deer sharing pastures in Northern Italy using the hair analysis. Aluminum, As, Cd, Cr, Ni, Pb, Cu, Mg, Fe, and Zn were quantified through the use of ICP-OES. Findings show As levels significantly higher in roe deer due to their selective feeding, while Cd and Pb levels align with other studies. Essential elements like Cu, Fe, and Zn are lower in cattle, possibly due to diet differences. Higher Cr and Ni levels in cattle suggest contamination or physiological differences in accumulation patterns. In conclusion, hair analysis is valuable for monitoring environmental PTE exposure, highlighting significant interspecies differences and the potential of both animals as bioindicators in shared grazing areas.
集约化养牛业面临的环境挑战正促使人们转向以牧场为基础的粗放型养殖系统，这影响了养分和污染物的吸收。潜在有毒元素（PTEs）是环境和生物体中常见的必需和非必需元素，其失衡会导致健康问题。毛发分析是一种非侵入性方法，可提供对PTEs暴露的回顾性评估。本研究旨在通过毛发分析了解意大利北部共享牧场的牛和狍中PTEs的暴露情况及物种特异性积累模式。通过电感耦合等离子体发射光谱法（ICP - OES）对铝、砷、镉、铬、镍、铅、铜、镁、铁和锌进行了定量分析。研究结果表明，由于狍的选择性觅食，其体内砷含量显著高于牛，而镉和铅含量与其他研究结果一致。牛体内铜、铁和锌等必需元素含量较低，可能是由于饮食差异所致。牛体内铬和镍含量较高，表明存在污染或积累模式上的生理差异。总之，毛发分析对于监测环境中PTEs暴露具有重要价值，突出了显著的种间差异以及这两种动物作为共享放牧区生物指示物的潜力。
